Hi Sandip. If you have use case such that you have described and you absolutely
must have an access to the current authenticated principal in the generic
success login view, here's one way to do that, relatively painlessly. Follow
these steps in your CAS maven overlay:
1) Bring cas-addons dependency into the pom:
<dependency>
<groupId>net.unicon.cas</groupId>
<artifactId>cas-addons</artifactId>
<version>1.0.5</version>
</dependency>
2) Define 'authenticationSupport' bean in the application context (this could
go into any Spring xml file under WEB-INF/spring-configuration):
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:c="http://www.springframework.org/schema/c";
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd"/>
<bean id="authenticationSupport"
class="net.unicon.cas.addons.authentication.internal.DefaultAuthenticationSupport"
c:ticketRegistry-ref="ticketRegistry"/>
</beans>
3) In WEB-INF/login-webflow.xml re-define 'viewGenericLoginSuccess' end state
like so:
<end-state id="viewGenericLoginSuccess" view="casLoginGenericSuccessView">
<on-entry>
<evaluate
expression="authenticationSupport.getAuthenticatedPrincipalFrom(requestScope.ticketGrantingTicketId)"
result="requestScope.principal"/>
</on-entry>
</end-state>
Then you should have org.jasig.cas.authentication.principal.Principal instance
under the 'principal' key in the request scope and you could access it in
casGenericSuccess.jsp like so:
<c:out value="${principal.id}" />
Hope this helps a bit.
Cheers,
Dmitriy.
